Is this really a concern? If you're awake, chances are you're dressed, and it can be on you. If you're lying down for the night, one presumes that's not someplace their kids will be directly accessing your belongings. In other words: Say goodnight, go to your assigned bedroom/sleeping area, close the door, go to sleep. Even with my own kids, in a hotel room or whatever, I can unload the gun, put it in the bedside drawer next to my pillow, and don't sit up all night worried they might get it out, load it, and shoot someone. A lockable case is nice for lots of reasons, though.
